Simple to operate, it has a self-centering mandrel, uses only eight sets of clamps for the full working range of the took, and is available either pneumatically powered or in a hydraulic version that adapts to most hydraulic power packs. The cutter blades are TiN coated and dissipate heat away from the pipe.
